Abstract
Abstract An inexpensive instrument for collection of genitourinary secretions, particularly for detection of gonorrhea in females is provided in practice of this invention. The elongated instrument has a head at one end for collection of samples from the cervical canal, and the other end has a head for sample collection within the urethra. In a preferred embodiment each head has a crescentlike cross section with an enlarged region on the convex side which tends to compress the wall of a body passage in which the head is inserted. A recessed region on the concave side exerts a decreased lateral pressure on the side of the passage. As the instrument is rotated within a passage the alternating increased and decreased pressures tend to ''''milk'''' various glands and ducts to induce and collect secretions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
135 words
A disposable genitourinary test instrument for collecting a specimen from a genitourinary passage by rotation therein to produce alternating increased and decreased pressures and thereby induce secretions from the glands therein; said instrument comprising, an elongated handle; a specimen collecting head located on one end of said handle; said head having a taper extending radially outward from the distal end of said head toward said handle and symetrically about the longitudinal centerline of said handle; and wherein said head has a general crescent lateral cross section shape substantially throughout its length; the concave side of said crescent shaped head having spaced end wall means extending laterally from said concave side of said crescent shaped head thereby defining a recess means for collecting said specimen when said head is inserted and rotated in said genitourinary passage.
Claim 2
Dependent Claim
135 words
A disposable genitourinary test instrument for collecting a specimen from a genitourinary passage by rotation therein to produce alternating increased and decreased pressures and thereby induce secretions from the glands therein; said instrument comprising, an elongated handle; a specimen collecting head located on one end of said handle; said head having a taper extending radially outward from the distal end of said head toward said handle and symetrically about the longitudinal centerline of said handle; and wherein said head has a general crescent lateral cross section shape substantially throughout its length; the concave side of said crescent shaped head having spaced end wall means extending laterally from said concave side of said crescent shaped head thereby defining a recess means for collecting said specimen when said head is inserted and rotated in said genitourinary passage.
Claim 3
Dependent Claim
28 words
A genitourinary test instrument as defined in claim 1 further including a frangible connection comprising a notch having a reduced cross section between said handle and said head.
Claim 4
Dependent Claim
26 words
A genitourinary test instrument as defined in claim 1 wherein said end wall means comprises three spaced walls and said recess means comprises two juxtapositioned recesses.
Claim 5
Dependent Claim
119 words
A genitourinary test instrument as defined in claim 1 further including another specimen head located at the other end of said handle, said another specimen head having a taper extending radially outwardly from the distal end of said head toward said handle and symetrically about the longitudinal center line of said handle; and wherein said another specimen head has a general crescent lateral cross section shape substantially throughout its length; the concave side of said crescent shaped another specimen head having spaced end wall means extending laterally from said concave side of said crescent shaped other head thereby defining a recess means for collecting said specimen when said another specimen head is inserted and rotated in said genitourinary passage.
Claim 6
Dependent Claim
36 words
A genitourinary test instrument as defined in claim 4 wherein said end wall means in said another specimen head comprises three spaced walls and said recess means in said another specimen head comprises two juxtapositioned recesses.
Claim 7
Dependent Claim
44 words
A genitourinary test instrument as defined in claim 5 further comprising a guard between said another specimen head and said handle said guard extending transverse to the length of said another specimen head for limiting the extent of insertion thereof into said genitourinary passage.
Claim 8
Dependent Claim
22 words
A genitourinary test instrument as defined in claim 4 further comprising a frangible connection between said handle and said another specimen head.
